Facebook fell in New York trading, bringing its decline to
about 29 percent since it went public in May, on concern the
social network’s sales and profit may grow more slowly than some
had expected.

Operating margin, excluding certain costs, was 43 percent
in the second quarter, a decline from 53 percent a year earlier,
amid a fourfold surge in expenses for sales and marketing,
Facebook said yesterday. Payments-related sales were $192
million, below the $199.3 million average prediction from
analysts surveyed by Bloomberg.

Operating profit in the three months ended June 30 rose 8.3
percent to 3.49 billion yen ($44.6 million), CyberAgent said
yesterday. That compared with the 5.2 billion-yen average of
seven analysts’ estimates compiled by Bloomberg.
